Indeed, and none too soon. Flash has always been an unpleasant proprietary stain on our mostly-open web (and far too many supposedly Free Software developers went along with that by making no effort to use, test or fix the free alternatives).
Helping kill it off is one the few good things Apple ever did for us.
It'll never be entirely gone, but I'd like to think that in 5 years time we can put the embarassing flash period behind us (assuming we can still get consumer hardware to run free code on, and haven't been ARM-UEFI'd to death instead).
